i3 Claims.

This invention relates to batteries and more particularly to a protector or cover for the connection of the battery cable to the terminals.

It is an object of this invention to provide a cover for the battery terminal and clamp to pre- 5 vent the corrosive effects of the acids and gases generated within the battery. In the common usage of battery clamps on the terminals, the

. fumes and acids from the battery will eventually onto the terminal post I I which is made of lead.

We have provided a cap or cover I8 which is adapted to encompass or enclose therein the terminal post II and clamp I4. The cover I8 contains therein a suitable chemical for counteracting the deleterious corrosive eiect of the fumes and acid.

The cover I8 is formed of aconcavo-convex body I9 having an upper wall 20 provided with a plurality of perforations 2l therethrough. A depending cylindrical outer wall 22 is provided about the lower end of the concavo-convex body I9.

One of the ends of the cover I8 extends beyond the body I8 of the cap to form a radial extension 24 thereof. The extension 24 is provided with a pair of oppositelyextending attaching ears 25 which may be formed` by cutting slots 26 in the depending side walls 22 adjacent the end of Still another object of this invention is to pro- 20 the projection 24.

vide a battery terminal protector of the lgind to be more particularly described hereinafter so constructed and arranged that it may be readily attached to the cable connected to the terminals whereby the device may be readily attached to `g5 the terminals and batteries currently in use.

With the above and other objects in view, our invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more par-gp ticularly pointed out in the appended claims. J

In the drawings,

Figure l is a top plan View of a battery terminal protector constructed according to an embodiment of our invention,

Figure 2 is a longitudinal vertical section 3 through the protector shown in Figure l, and

Figure 3 is a top plan view partly broken away showing the attaching ears inv their extended position.

Referring to the drawings, the numeral I0 des- 4 ignates generally the case of a battery having a terminal post II thereon. While all of the batteries are formed with the positive and negative The upperends of the slots 26 may terminate at the. juncture of the outer wall 22 and the portion of the upper wall 20 on the extension 24.

The ears 25' are adapted to be clamped about the cable I2 behind the 4clamp I4 for attaching the cover vI8 thereto. The ears 25, preferably made of the same material as the remainder of .the cap I8, have a certain degree of resilience enabling them to be spread for removal of the terminal posts, in the drawings only one post II 4 D is shown.

'I'he battery cable I2 is attached to the post II in a conventional manner by a clamp I4 fixed on the end of the cable. The clamp I4 may be of any conventional style having a pair of clamping arms I5 and I6 connected together by a 5 clamping bolt or pin I'I.

In the use of a terminal clamp of this type the acid and fumes from the battery will frequently cause corrosion of the clamp usually made of steel whereby the clamp will become frozen 55 cover from the cable when desired.- p

A semi-circular horizontal liange 2l is lixed to or formed on the lower end of the side walls 22 on the cap,I8 at the end thereof opposite from the extension 24. The flange 2'I is adapted to underlie the clamping members I5 and I6 of the clamp I4 for positioning the cap or protector I8 about the clamp I4 and post I I. In this manner the side walls 22 of the cap IB are positioned completely about the post II and clamp I4.

Interiorly of the cap I8 I have secured a pad 28 to the wall 20 which may be made of felt or other suitable fabric or porous material. The pad 28 is impregnated with bicarbonate of soda or other suitable chemical for counteracting the corrosive effects of the fumes or acid from the battery I0.

The pad 28 is secured to the lower surface of the upper wall 20 of the cap I8 and is adapted to close the openings or apertures 2| therethrough. Since the pad 23 is porous, the gases or liquids are not restrained from passing through the perforations 2I but will be forced to penetrate through the pad 28 as the gases or liquid flow through the cap.

While bicarbonate of soda has been found to be a suitable chemical for counteracting or pre- 3 venting the corrosive eiect of the fumes and gases from the battery which are generally sulphuric acid and the resulting gases, other suitable chemicals may be used.

We do not mean to conne ourselves to the exact details of construction herein disclosed but claim all `variations falling within the purview of the appended claims.

Having thus described our invention, what we claim is:

1. An anti-corrosion device for association with a storage battery post and a batterycable having a clamp surrounding the post, said device comprising an inverted pan-shaped circular body larger in diameter than the postand the surrounding clamp and adapted to be substantially concentrically superimposed thereon, said body comprising a peripheral wall to depend in protective relation to the sides of said clamp and post, said body having a radial projection ar- 'ranged to protectively overlie 4tl'ieibattery cable Ladjacent 4'to the clamp, said projection having earsadapted to bebent around the cable, a por- 4tion of said peripheral 'flange opposite said'radial vprojection having a radially inwardlyprojecting "flange arranged Ato engage beneath an adjacent part of the cable clamp so as to cooperate with #said-ears inholding the device in place, vthetop "wall of said bodylbeing formed with holes, vand xa -porous pad secured to 'theunderside of said "top wall'and occluding said'holes Vand containing Aanti-corrosion material.
